The invention concerns a suspension stop device, for a motor vehicle driving wheels, comprising a filtering block, consisting of an upper housing fixed relative to the vehicle body and co-operating with a lower housing mobile in rotation about a shock absorber rod and supporting a suspension spring, and a ball bearing. Said upper (21) and lower (23) housings are made of thermoplastic material and have opposite surfaces hollowed out in a circle, about the rotation axis (d) of the shock absorber rod (24), to receive a raceway for the ball bearing (22). The upper housing (21) further incorporates an impact stop (42) moulded around the leading stop (41) of the shock absorbing device, and the thermoplastic structure of the upper housing (21)is reinforced by a ring (45) made of overmoulded elastomer.
